Use a column decorator.
<display:column property="commissionAmount" title="Commission"
decorator="com.whitesandsolutions.gapay.view.decorator.MoneyDecorator"
sortable="true"/>
And create your decorator class something like this:
public class MoneyDecorator implements ColumnDecorator {
public MoneyDecorator() {
super();
}
public String decorate(Object value) {
String decoratedValue = "";
try {
if(value != null) {
// Assumes the value is a Double.
decoratedValue =
DataFormatter.formatMoney(((Double)value).toString());
}
} catch (Exception e) {
e.printStackTrace();
decoratedValue = "Format error.";
}
return decoratedValue;
}
}

Subject: Displaytag, number formatting, and sorting
Hi all,
I am using displaytag, and I would like to have a sortable column of
large numbers. I want to format these numbers (they're going to be
dollar amounts, like 1,400.00, 6.99, and the like), but it seems that I
cannot have the fancy number formatting and have that column sortable
all at the same time. I either get a sortable column of numbers that
look like this:
1400.00
33938.39
3450984530.83
.99
...or a non-sortable column of nicely formatted numbers, like this:
1,400.00
33,938.39
3,450,984,530.83
.99
Has anyone been able to get the number formatting and the sorting to
work together? If so, please tell me what I'm doing wrong. I've tried
bean:write with a formatKey, html-el:rewrite, and whatever else to no
avail.
Thank you very much!
Andy
